Question

我一直无法创建ASP.NET MVC程序，该程序将随机选择一个学生并随机选择一个问题，由于某种原因，我无法在.cshtml文件中使用它。难道我做错了什么？我也得到这个错误

“传入字典的模型项目类型为'QuizProgramMVC.Models.Student'，但此字典需要一个类型为'QuizProgramMVC.Models.StudentQuestion'的模型项。”`使用QuizProgramMVC.Models;

控制器

public class QuizController : Controller
{
    public QuizController TheQuiz { get; set; }

    // GET: Quiz
    public ActionResult Index()
    {
        StudentQuestion sq = new StudentQuestion();

        return View(sq);
    }

    public ActionResult QuizProgram()
    {        
        Student program = new Student();

        return View(program);
    }

}

查看

@model QuizProgramMVC.Models.StudentQuestion
@using QuizProgramMVC.Models;

@{

    Layout = null;
 }

Answer 1

问题是您使用不同的模型调用相同的视图页面。

public ActionResult QuizProgram()
{        
    Student program = new Student();//Here you need to pass the StudentQuestion to the view.
    return View(program);
}

通过 QuizProgram（）调用上述视图页面（.cshtml）会引发错误，因为在该视图页面中您将模型定义为

@model QuizProgramMVC.Models.StudentQuestion

它不允许其他ViewModel，因为它是强类型视图。
